(Video) Pittsburgh Penguins edge out Boston Bruins in 2-1 win

The Pittsburgh Penguins extended their winning streak to nine games with a 2-1 win over the Boston Bruins on Sunday, and in the process took sole ownership of top spot in the East.

First period goals from Sidney Crosby and Joe Vitale sealed the win, while Tomas Vokoun was also instrumental as he made 31 saves to preserve Pittsburgh’s lead.

The Bruins’ goal was just the fifth conceded by the Penguins in their last five games, as they shut-out their opponents in the final two periods to ensure they improve their record to 22-9-0 for the season.

What made the win even more impressive was that it arrived when the Penguins were missing leading defenseman Kris Letang and reigning League MVP and scoring champion Evgeni Malkin.

Their absence will be a worry moving forward, but for now Pittsburgh are out on their own at the top of the Eastern Conference.
